DeepSeek Harness Plugin

OrderG-X/dsh-video-preview

Category UI Enhancements Added 2026-10-17

Plays local video and audio inside the conversation. A play_video tool renders a native player at the tail of the turn - under the model's final output, no click needed - streamed over HTTP Range so long files seek instead of loading into memory. Also registers a sidebar media preview renderer, since the built-in previewer treats mp4 as unviewable.

Install

# from a prebuilt release tarball

dsh plugin --profile web add "https://github.com/OrderG-X/dsh-video-preview/releases/latest/download/dsh-video-preview.tgz"

# from GitHub (first run asks for allowBuilds approval — follow the hint, retry)

dsh plugin --profile web add github:OrderG-X/dsh-video-preview

Any plugin you install runs third-party code with your own permissions — it can read your files, use your credentials, and reach the network, and tool approvals don’t sandbox it. GitHub-sourced plugins also run build scripts at install time — pnpm blocks those until you allow them, so an install can stop with ERR_PNPM_GIT_DEP_PREPARE_NOT_ALLOWED or ERR_PNPM_IGNORED_BUILDS; dsh prints the exact key to add under allowBuilds in your profile’s pnpm-workspace.yaml, and the install works on the next run. Allowing a build is a trust decision: only install sources you trust, and pin a commit (github:owner/repo#sha).
